Final answer:
In the variation equation M = 2t, when the value of 't' is doubled, the value of 'M' also doubles.
Step-by-step explanation:
A variation is a relation between a set of values of one variable and a set of values of other variables. In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.
In the variation equation M = 2t, 'M' stands for the dependent variable and 't' stands for the independent variable. When t is doubled, according to the equation, the value of M should also double. If for example, when t=1, M equals 2. So, if t is doubled and becomes 2, M would now be 2 * 2 = 4, which is double the original value of M.
